exits normally. This must be one of Integer.TYPE, Double.TYPE, Float.TYPE, BigDecimal.class, CharSequence.class.onEmpty - defines the action to be taken if the expression evaluates to the empty sequence.
May be null if the expression is known statically not to evaluate to an empty sequence. If the return
class is a primitive type (double, float, etc) this must be an instance of OnEmpty.UnwindAndJumpCannotCompileExceptionpublic void compileToPush(CompilerService compiler, Expression expression) throws CannotCompileException
